Approved by Westminster City Council, the 2,300m2 scheme will replace the existing Odeon West End cinema and will house a 240-bed hotel, luxury apartments, street-level cafes, and a rooftop restaurant.
The circular tower will be clad in mirror-finished stainless steel and is reminiscent of the practice’s doomed Spiracle tower in Leeds – which was dubbed the 'Stack of Poppadoms' – albeit shorter.
A spokesperson for the Leicester Square Co-ownership Group said: ‘This will be a major focal point for Leicester Square – bringing new life into a neglected corner of one the London's landmark destinations and drawing people down to the National Gallery and Trafalgar Square.
‘It will be an important contribution to the wider improvements to this area and help to connect two of the capitals most popular public spaces.’
Work is expected to start on site next summer (2009).
